Cementing operations present various difficulties attributed to shallow flows all around the world. Cement ability to seal the annular space, aids in sustaining the well integrity by mitigating and preventing fluid migration to other formations and t

Liner hanger seal assembly and cement sheath are essential barrier elements for well drilling and completions. During installation, the liner hanger seal assembly is set up-stream to the cement column. This arrangement prevents the evaluation of both

One of the multiple barriers that is installed in the downhole during drilling and completion is the liner hanger seal assembly. The liner hanger is used to engage the liner, connect it to the previous casing, and seal off with cement before a pressu

Drilling fluid loss and mud filtration occur concurrently during overbalanced drilling. Characterization of fluid loss is mostly done via experimental studies with several types of setups and porous media. The first part of this study has been conduc

Elastomer seals are essential for zonal isolation in vertical and deviated wells. They are often used either as O-rings (static seals) or as energized seals (packers). For elastomers to perform their functions effectively over an extended period, it

Drilling mud filtration occurs during an overbalanced drilling activity and concurrently with mud loss through pore throats and fractures. Mud loss and filtration are increased when the wellbore fluid condition is in a dynamic mode (pipe rotation and

Lost circulation events and mud filtration in drilling operations have been investigated over the years because they lead to non-drilling time (NDT) and increase the overall well cost. Solutions have been offered from the addition of fluid loss contr

Offshore drilling operations exhibit various difficulties attributed to shallow flows worldwide. One of the most common practices for drilling offshore wells is to use liners and liner hangers rather than using full casing strings. This reduces the c

Drilling fluids Invasion and mud filtration is a complex process that is influenced by several variables, and has NPT (Non-Productive Time) implications. Most of these variables are either within operational control limits (mud type, LCM type/concent
